eM Client Custom Search Not Excluding All Mail Folder

eM Client 10.1.4417 (c2d4b18)

Using the search function I performed the following:

. Used custom folder option
. Select folders for an account
. Unchecked ALL MAIL folder
. Enter search words in HAS WORDS field
. Entered my e-mail address in FROM field
. Entered my e-mail address in TO field
. Clicked on SEARCH button at bottom right

The search took some time, which was expected, and came up with one message. Right clicking on the message and selecting properties resulted in the folder being ALL MAIL. I confirmed that the message also was found in another folder.

It would appear that the unselected folder in the CUSTOM FOLDER (unchecked) is included in the search and that other folders are ignored once the first is found.

Please advise what may be happening.

Thank you.

Terry
